When a user clicks "Forgotten your login details?" on a MediaWiki wiki currently and successfully submits a valid username, the wiki outputs:
A reminder e-mail has been sent.
This is wrong. It is not a reminder e-mail. The user already knows his or her username and the e-mail does not (and cannot) contain the user's password. The word "reminder" is simply wrong, I believe.
In the e-mail body text itself, it reads:
Someone (probably you, from IP address ...) requested a reminder of your account details ...
This should also be changed.
